Installation Notes
Pre-Installation Checklist:
1.Component Inspection: Verify part number (082V04200-6031) and check for cracks or deformation
2.Cleanliness: Ensure rocker arm shaft and contact surfaces are free of debris and oil residue
3.Measurement: Check rocker arm bore diameter and shaft clearance (0.02-0.05 ມມ)
4.Lubrication: Apply clean engine oil to rocker arm bore and contact points before installation
Installation Steps:
1.Positioning: Slide rocker arm onto shaft with lubrication hole aligned with oil passage
2.Alignment: Ensure rocker arm sits evenly on valve stem and pushrod
3.Torque Specifications: Tighten rocker arm shaft bolts to 85 ± 5 Nm in specified sequence
4.Valve Lash Adjustment: Set valve clearance to 0.25-0.30 ມມ (cold engine) using feeler gauges
Critical Warnings:
Never reuse old rocker arms; replace in sets per cylinder
Avoid over-tightening; use calibrated torque wrench for accuracy
Verify proper oil passage alignment to prevent lubrication failure
Check valve stem tips for wear before installation
Post-Installation:
Prime oil system before initial startup
Run engine at idle and check for unusual valve train noises
Re-torque rocker arm bolts after first 500 km of operation
Monitor valve clearances during initial break-in period
